LABELING-MACHINE.

To all whom it may concern:

' Be it known that I, WALTER R. WULFEOK, a citizen of the United States,and a resident of Cincinnati, county of Hamilton, and State of- Ohio,have invented a new and useful Improvement in Labeling-Machines, ofwhich thefollowing is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a partof thisspecification.

My invention relates to, and has for its object, the construction of alabeling machine in which the paste is first spread over the entiresurface of the reverse side of the label, and the label, while in amoist and pliable condition, is then applied to the can or other vessel;the liability of the label to be torn off, where the adhesive is appliedto only a portion of the back, is thus overcome, as is also the failureto adhere when not previously moistened, as where the adhesive isapplied in the first instance to the surface to which the label is to beattached.

In the drawings: Figure 1 is a front elevation with parts omitted forthe sake of clearness. Fig. 2 is an end elevation. Fig. 3 is a rearelevation with the paste smoothing roller omitted. Fig. 4 is a detailedview of the can carrying rack. v

The numeral 1 indicates the frame and supporting standards ofmy'machine. Supported between said standards is the table 2, upon whichthe labels are stacked, with the backs upward. Said table is arranged toreciprocatein a vertical plane, and is centrally mounted on a shaft orplunger 3, the lower extremity of which extends through a hole in aplate 4:, also supported between said standards. A coil spring 5, aroundsaid plunger and bearing upon said plate 4 and the bottom of said table,maintains the latter normally at a proper elevation for applying alabel, previously supplied with the necessary adhesive, to the can orother vessel. The elevation of said table is adjustable by means of anut 6 on the end of said plunger, below said plate. In order to preventthe table 2 from tilting, said table is provided with shoulders 7 on atleast two of its edges, which work inslots in the plates 8, said platesbeing also mounted between the standards. To cause said table toreciprocate in a vertical plane at the required intervals, I provide onthe bottom of said table Specification of Letters Patent. Patented J 1 16, 1911, Application filed June 9, 1910. Serial No. 566,032. i

and near theends thereof, the blocks 9-9, each of saidblocks beingprovided with a slot; .in these slots the cams 101(), eccentricallymounted, by means of links 11, on the wheels 12, work, to lower thetable against the pressure of the spring 5. The cams 10 are preventedfrom rising when driven inwardly into said slots by shoulders on .saidcams, which slide against correlated shoulders on the blocks -13,mountedon thestandards 1; and the cams are thus compelled to take effectagainst the bottoms of the slots in the blocks 9, thereby lowering thetable. The wheels 12 are connected on shaft 1414, supported by hearingson the standards, and these shafts, are driven, through theintermediation of the shafts 15, 16 and 17, also mounted in suitablehearings on the standards, and appropriate bevel gears, by the mainshaft 18. From the above it will be seen that at each revolution of thewheels 12, the cams 10 will be forced into, and again withdrawn from,the slots in the blocks 9, V

and the table 2 will thus be lowered, and, upon the withdrawing of thecams, will rise again, actuated in the latter movement by the spring 5.

Mounted in suitable supports on therear of the frame 1, is the pastetrough 19, within which a roller 20, is driven, through theintermediation ofthe shaft 21 and appropriate bevel gears," bythe mainshaft 18. In back of said roller 20 isia smaller roller 22, which bearson, and is driven by, said roller 20, for the purpose of smoothing anylumps in the paste gathered by said roller 20. J ournaled in supports onsaid frame, and at the rear of the paste roller is the shaft. 23, drivenby a belt from the pulley 2 1 on the shaft 16. Said shaft 23 carries oneach of its ends an arm25, the free ends of said arms being connected,by means of links 26 to the ends of the paste distributing roller 27.Said roller 27' is mounted in the slotted frame or rack 28, supported onthe standards 1, in which rack said roller reclprocates, when actuatedby the turning of the arms 25 from a point contacting with the roller 20to scribed; when said table is up, however, it is above the level ofsaid rack. For the purpose of holding the labels firmly on the tablewhile the roller 27 is passing over and pasting the upper label, thespring clamps 29 are provided. These clamps are pivotally mounted onrods between the standards, and are so balanced by weighting the lowerportion, that normally the clamping end will be out of the path of thetable. A cam surface, 30, on the upper side of each of the cams 10,raises the lower portion of each of said clamps, however, simultaneouslywith the lowering of the table, and causes the upper portion to descendinwardly and over the edges of the top label, clamping the labels asdesired, and preventing the paste distributing roller from dislocatingor removing the same.

At one end of the table 2, and on a level with said table when up, isthe rack or frame 31; said ra'ck extends to the edge of said table, andserves to convey the cans or other vessels thereto. A similar rack 32leads from the opposite end of the table to carry the cans therefrom,after said cans have been properly labeled. Each of said racks isconstructed of two angle bars with the necessary cross-bars at suitableintervals, as shown in detail in Fig. 4; and said racks are adjustableto meet the size of the vessels to be labeled by means of bolts whichconnect said angle bars and said cross-bars, and slots in said anglebars at the points of connection, as shown. The heads of the bolts aresunk so as not to interfere with the passing of the cans. The receivingend of the rack 31 forms a chute 38, toward a depressed portion, whichserves as a sort of rest for the cans; within this depression 1 thespacing wheel 34L is rotated by a belt from a pulley on one of theshafts 1 1. Said spacing wheel delivers the cans at suitable intervalsto the main portion of the rack, where they are carried along byfriction of the belt 35, which travels around the pulleys 86 and 37,pulley 36 being mounted on a shaft driven by a belt from a pulley on thespacing wheel shaft. Within the belt 35, near each end of the table 2are heavy idlers 38 and 39; these are mounted in slots in supports 40and 41 on the racks, and serve to hold the belt firmly against the can,while said can is passing over the table to receive its label. Beneaththe rack 32 is a steam coil 42 for the purpose of drying the paste onthe labeled cans w hile said cans are passing through said rack justbefore delivery.

The operation of my new labeling machine is as follows: The cans beingplaced by the operator in the chute are taken up, one at a time, by thespacing wheel and delivered at the proper intervals to the point wherethey are acted upon by the belt 35. While traveling through the rack 31,the table, stacked with labels, is lowered as above described, and thepaste distributing roller passes over the table, applying a coat ofpaste to the uppermost label, so that when the can reaches the end ofthe rack 31, the table, having reascended, is again in its elevatedposition with a wet label on a level with said rack. Over this label thecan then passes, the label adhering thereto as will be readilyunderstood; and before said table is again lowered, the labeled can isdelivered to rack 82, where it passes over the steam coil 42 and isdried.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a labeling machine, the combination with a reciprocating table, ofa reciprocating paste-distributing roller, the movements of said tableand said roller being adapted to cooperate, said table and said rollerperforming each a complete double stroke during each operation of saidmachine, said roller intersecting the line of reciprocation of saidtable above said table and in a plane substantially parallel thereto.

2.
